## Is Winner
### Instructions
Create a function named `isWinner` which accepts a string representing the name of a country. It should use the `winners` _"API"_ to return a resolved `Promise` with an appropriate string.
The strings which can be returned are listed below. You'll need to replace `"Country"` with the country named which is passed to `isWinner` :
- `"Country never was a winner"` : The country has never won a FIFA world cup.
- `"Country is not what we are looking for because of the continent"` : The country is not from the european continent.
- `"Country is not what we are looking for because of the number of times it was champion"` : The country won the FIFA world cup fewer than 3 times.
- `"Country won the FIFA World Cup in <years> winning by <results>"` : with the following format:
- `<years>` : `"1000, 1004, 1008"`
- `<results>` : `"4-3, 5-2, 1-0"`
